State-run TV reports Mehsud was injured in drone attack and died last week

Mehsud has been target of suspected U.S. drone attacks in Pakistan

Islamabad, Pakistan (CNN) -- The Pakistani military on Sunday was looking into a local report that the region's Taliban leader had died, officials said.

State broadcaster PTV reported that Hakimullah Mehsud, the Taliban commander in Pakistan, was wounded in a drone attack this month, and that he died and was buried last week. PTV cited local sources and its correspondent in North Waziristan.

A Taliban source denied the report to CNN, saying that Mehsud has simply gone "underground" after being targeted by drone attacks.

The source, who requested anonymity because he is not an authorized spokesperson for the Taliban, said Mehsud is alive and well and will release a taped recording to prove as much.
